We're dividing 735709 by 72 
The aim is to understand the frequency of 72 in 735709.

Let's proceed to step 1:
72 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 72

On to step 2:
73 divided by 72 is 1 with a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 72 from 73, we get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 72

Moving on to step 3:
If we divide 15 by 72, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 10.0
The remainder is 15 after subtracting 0 from 15.
Take the next digit (7) from the dividend and append it to 15, then repeat: 157 / 72

Going ahead to step 4:
157 divided by 72 is 2 with a remainder of 13.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Subtract 144 from 157 to get 13.
Take the next digit (0) from the dividend and append it to 13, then repeat: 130 / 72

Advancing to step 5:
72 goes into 130 1 times with a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 1021.0
If we take 72 away from 130, we end up with 58.
Grab the next digit (9) from the dividend, add it to 58, then carry on: 589 / 72

Advancing to step 6:
589 divided by 72 is 8 with a remainder of 13.
The next digit of our result is 8. 
Result so far: 10218.0
Deduct 576 from 589 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
130 divided by 72 is 1 with a remainder of 58.
Use 1 as the next digit of our solution. 
Result so far: 10218.1
The remainder is 58 after subtracting 72 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 8:
When dividing 580 by 72, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 10218.18
Subtracting 576 from 580 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
40 divided by 72 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 10218.18
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
72 can be fit into 400 5 times, resulting in a remainder of 40.
The next digit of our result is 5. 
Result so far: 10218.1805
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
72 goes into 400 5 times with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 10218.18055
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

After the division, we end up with 10218.18055 and a remainder of 4e-05.
